DOCUMENT-FILE.

SPECIFICATION forming part of Letters Patent No. 461,781, dated October20, 1891. Application filed July 27, 1891- Serial No. 400,829. (Nomodel.)

To all whom it may concern.-

Be it known that I, ALEXANDER DOM, a citizen of the United States,residing at Mount Healthy, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Document-Files, ofwhich the following is a specification.

In the accompanying drawings, forming a part hereof, Figure 1 is aperspective view of my improved file in an operative position withdocuments filed therein. Fig. 2 is a side elevation of the file shown inFig. 1, with its clamp-board and clamp slid backward on the clamp-bar inposition to examine the documents, the dotted lines indicating the p'osition of the said clamp-board and clamp when in use to retain saiddocuments in proper position. Fig. 3 is a central transverse sectionthrough the base, clamp-bar, and stay-rods, looking toward theclamp-plate or follower, when in use, as shown in Fig. 1.

My improved document-file is preferably constructed as follows: The baseA is provided with a central longitudinal groove, having therein acentral supporting tongue or rib a, on which latter the clamp-bar Brests, as more clearly shown in Fig. 3, said rib being cut away at itsfront end portion to permit said clamp-bar being rounded down over theend thereof, and thus afford a stop for the clamp in its forwardmovement, as shown in Fig. 2. This clamp-barBmight be rounded down ateach end and secured within this central groove without the central riba; but in order to more securely retain said bar to place it ispreferred to employ the rib, to which the former is screwed or otherwiseconnected.

The clamp D is preferably formed, as shown, with the lowerinwardly-projecting flanges (Z, (see Fig. 3,) which latter engagebeneath the outer edges of bar B. This clamp is also rounded inwardacross the top of said bar, thus forming shoulders (Z which latter, inconnection with the flanges d, serve as guides for the clamp proper asit slides back and forth on the bar B. TheclainpD is connected to theclamp-plate or follower-E in such a manner as to permit of a slightrotary movement of the latter, and for that purpose I prefer to connectsaid parts by means of a the front end thereof, as shown.

staple e, passed through suitable openings,

formed in the top portion of said clamp and secured to said plate. Anyothersuitable device may be employed for affording the desiredconnection between clamp D and its plate E.

To the rear end of base A is connected the vertical end piece F, thelatter being braced at its top portion by means of stay-rods G,connected at one end to said end piece and at the opposite end connectedto the base, near The stayrods G, in connection with base A and end F,form the body of the filethat is, the documents are inserted betweensaid stay-rods, and are securely clamped to place between the end pieceF and plate E, in the manner now to be described.

The operation of my improved file is as follows: The documents, afterhaving been properly marked or stamped, are inserted, as shown, betweenthe clamp-plate E and end piece F, the rods G tending to retain saiddocuments in a vertical position, after which the said plate and-clamp Dare moved rearward, securely compressing the documents against the saidend piece. After the desired pressure is had the clamp-plate and clampare retained to place by means of the flanges cl locking or engagingwith the bar B, thus producing a friction-lock. To loosen theclamp-plate, all that is required is'to slightly press the latter nearits top portion and then grasp the clamp D near its bottom portion, saidoperations tending to disengage the flanges d from a locked position, atwhich time said clamp and plate are free to slide forward, theturned-down end of bar B effectually preventing said clamp from slidingoff its bar. l/Vhen examining the documents, the clamp-plate E assumesan inclined position, as shown in Fig. 2, against which the documentsrest after having been examined, and are thus kept in position to bereadily and quickly righted and clamped to place in the manner aforedescribed.

The advantages of my improved documentfile are apparent. Theconstruction of the clamp for retaining the plate E in proper positionis such that the latter cannot fall upon the,base A, as the flanges dand shoulders d tend to retain said clamp and plate in an approximatelyvertical position. The clamp, after having been secured to place on itsbar B, cannot become disengaged therefrom, and is always in an operativeposition. The stayrods, in addition to bracing the end piece,

- also form the sides of the file, thus producing A document-fileconsisting of base A and an end piece F, connected thereto, clamp D,follower E, and clamp-bar B, said base having a longitudinal groove witha rib Cb centrally therein, on which the said bar is connected, theouter edges of said bar overlapping said rib and bent down over thelatter at one end thereof, the clamp having integral inturned flanges dand shoulders (1 respectively engaging beneath and above said bar B ateach side thereof, said clamp at its upper portion being connected tothe follower by a staple e, substantially as set forth.
